GUE - Fundamentals (Fundies)


The GUE Fundamentals course is by far GUE’s most popular program. It functions as a gateway into GUE training and it is an excellent way to personally experience what GUE is all about.

Some divers use the Fundamentals course as a way to improve on the less-than-optimal training they have received during traditional fast-track entry-level courses. Others see the course as a ticket to participate in GUE projects and activities. Many technical divers and even experienced instructors from other organizations use the course to improve basic skills and gain access to GUE’s cave and tech-training. It is not uncommon to have divers with very diverse backgrounds in the same class, which makes this course completely unique in the diving industry. Everybody will benefit, regardless of their current level of certification or experience. Graduating this course with a pass is something to be proud of, as the quality of a GUE Fundamentals diver is recognized all over the diving world.

For many non-GUE divers, the Fundamentals course is an “aha!” moment where everything falls into place. The standardized equipment configuration and standardized procedures are only a small part of the big picture. Realizing how a team-oriented approach can free up resources and increase situational awareness that can be used to maximize safety, efficiency, and fun is often a life-changing moment for Fundamentals students, and they walk away from the course with a completely new approach to diving.

Historically, the Fundamentals course was created to make sure that divers who showed up for more advanced training in GUE’s cave and tech courses were not struggling with basic diving skills. A solid diving platform is based on balance, trim, buoyancy and propulsion techniques. It is pointless to begin more advanced training before mastering these basic aspects of diving. It will only lead to over task loading, stress, and poorly-learned skills. Divers who struggle with personal skills will not be able to contribute to the team, nor will they have the required level of situational awareness needed in cave or tech training.


The GUE Fundamentals course provides all divers with an opportunity to advance basic diving skills. It provides the non-GUE trained divers (divers who are already certified with another recognized diving agency) with a gateway into GUE training.

It is a prerequisite for all GUE courses (apart from entry-level courses, Drysuit and Doubles primers).


Course outcomes include, but are not limited to: GUE equipment configuration and use, trim and buoyancy, propulsion techniques including backwards kick, valve management (the course can be done using a single tank or with a double tank configuration), gas sharing, and SMB deployment.

This course will supplement training that divers may have already received and will give them more confidence in their basic skills even if they do not desire to go on for more advanced training. The course also includes the theory and use of nitrox.

Tech Endorsement

What Is It Needed For?

The Technical Endorsement is a workshop that will evaluate divers' skills required to enter GUE's technical and cave curricula.

The workshop is for all recreational GUE divers and divers certified on a recreational GUE Fundamentals level who are also competent in use of doubles and primary light, and also possess rescue skills. Divers entering this evaluation possess exemplary trim and buoyancy skills. 

The Technical Endorsement can be earned during GUE Fundamentals, Recreational Diver Level 2 and Level 3 courses, or during any other foundational training. Positive completion will allow divers to enroll in GUE's Technical Diver Level 1 or GUE's Cave Diver Level 1 courses.
